The forecast from FOX 17 Weather Ready Chief Meteorologist Kevin Craig: A hot and humid weekend is ahead with highs in the 90s and heat index values between 98 and 105 degrees! We remain under a HEAT ADVISORY through Sunday, and it will likely be extended into at least Monday. There is also a CLEAR AIR ACTION DAY in effect on Saturday for high surface ozone levels and poor air quality. Make sure to stay cool and hydrated! The overall pattern hints at much warmer than "average" through the last week of June. Watch out for high waves on Lake Michigan this weekend too! Winds will drive high waves, dangerous for swimming from time to time, and likely small craft advisories for boaters. Stay tuned to the FOX 17 Weather Ready Team for your latest forecast updates.
